De it known thatI, THOMAS E. HALL, a citizen of the United States, residingat Chicago,

in the county of Cook and Stateof lllinois have invented a certain new and useful Improvementin lllcdicameut-Iujectors, of which the following is a specification.

This invention has for its primary object the construction of'an injector by the. use of which the application of medicament either inthe form of dry powder, vapor, or liquid can be attained in the passages of the human body and have such application made under the proper conditions and requirementsfor obtaining the most beneficial resultsaud have the discharge ofthe medicament when in the form of powder insured withoutbeing lumpy or adhering together. 1 d

The invention 'consists inthe features of constructionfaud combination of parts hereinafter described and claimed.l

In the drawings, Figure 1 is a side elevation of thc injector of the invention in the pre ferred form for use in applying medicament in the form of powder; Fig. 2, a central longitudinal section of the injector shown in Fig. 1 with the bulb removed; Fig. 3, a side elevvation showing an arrangement of the injector for use with the nasal passages in the application of a liquid or vaporous medicament; Fig. 4, a central longitudinal section of the construction shown -in Fig. 3, and Fig. 5 a central longitudinal section showing a modified form of the injector for use in applying a liquid or vapor medicament to the nasal passages. The bulb for producing the compression to eject the liquid is not shown in Figs.

2, 3,4, and 5, but i the same construction as shown inFi". 1. l

The injector is constructed with a compressible bulb a, made of india-rubber or other suitable material and having at one end an inlet-port b, valve-controlled, and having at the other end an outlet-port c, likewise valve-controlled, as usual'in'the construction 'of compressible bulbs. v A tube c1, preferably rubber, is connected with the outlet c at. one cndand atits other end extends vthrough a. cork or stopper e, having, as shown, a rigid 5o cap e", and this stopper is entered into a tube f, made of any suitable rigid' material, and,

as shown, the tubefin the eonstructionshowr in Figs. 1 aud 2 preferably has its entering end f' on an incline, which is a preferred form for use in the passage of the vagina The construction of Figs l and i' has locat/ec in thel tubefa -wall or plug g, the inner enf of which,'as shown, is of afuunel orin'wardlydepressed formation, and between this wall or plug g and the cork or stoppere is a cham ber 7i for the reception of powdered medica nient. The plug or wall g has entered there Vinto so as to communicate with the funnel' shaped opening a stem 1', having at its ent' a. discharge-nozzle i' of a' pear shape with: fine perforation in its end. The pear-shape( bulb or enlargement of the discharge-stem bj its conical shape forms a chamber agains the wall of which the powdered medicament will be projected bythe forceof the dischargi derived from the air forced from the com pressible bulb for the impact of the powderet medicament agen t the wall of the chambe;

liabilityof causing irritation from any lump:

or adhesion of the particles one to the other and in addition this breaking up of the lump; condition and sprcadingof the adhering par ticles prevent the stoppage of the dischargl orifice or perforation by lumps or adhering particles, making the operation of the injec tor in discharging the particles properly am the application of the powdered medicamen tothe to-be-treated part a vfinished and reli able one.

The construction shown in Figs. 3,4, and:

Ain place of. the solid wall'or plug g employ a stop j, preferably of sponge or other snit able porous material, and between this stop, and the cork or stopper' e a chamber simila vto chamber h is formed, in whichrchambe liquid will be placedgfAv The'construction o Figs. 3, 4, and-5 has inserted int'he discharg end. of the tubel f a vcork for plug k, am through this cork is entered the end of Atw'` stems?, preferably of flexible material, lik india-rubber, and each tube l at its onterxu struction of Figs. l and ifree endkhas ailixed thereto a discharge-nozzle T, preferably of a pear' shape, for the -same reason and for the samepnrpose as described for the discharge-nozzle i' in t-he con- The tube f2 ,in the construction shown in Fig. 5 is foreshortcned; lint otherwise the construction and arrangement arevth'e same as shown and described forFigs. 3 and 4.

lo' The powdered medicameutin the construction of injector shown in Figs. 1 and 2 is placed in the chamber h by removing the cork or stopper 6,-and when the required lamount of powdered medicament is in the l5 chamber the cork or stopper is replaced and the injector or instrument is ready for use. In use the tube f is entered into the vaginapassage or other passage of the body where .the treatmentis to be applied, and when inzo serted to the extent required the bulb av is com pressed, f orc'in gthe airtherefroxn through thetube d for the pressure of the air to act ou the powdered medicament in the chamber h and force such medicament into the stem to bedischarged in a sprayed `form at the discharge end of the nozzle i' into the chamber of 'the tube f forward of the nozzle and passed. therefrom on to the part to be treated by, the medicament. It more than one discharge of 3o the medicament is required at one operation,

the cork or stopper can. be removed and a new charge of the powdered medicament placed in the chamber hand the cork or stopperreplaced =for another compression of the 5 bulb to eject the powdered medicament in a spray or sprayed-out form at the discharge end of thctubefdirectly at the point where the application of the medicament is to be made. A single compression of the bulb 4a will ordinarily be suilicient to project the charge entered in the 'chamber 7i; but it will be understood that if a single compression is not sniiicicnt for the purpose the bulb can be compressed as many times' as may be required.

The operation of the injector for usev in treating the nasal passages is essentially the same as described for treating other passages of the human body, except that the liquid or 5o vaporous mixture is placed in the chamber of the tubef, and this liquid or vaporous mixture is forced through the porous material forming thefabutment in the tube by the pressure of the air and Vis injected into the disehargemozzle l' to be projected therefrom,

` it being understood thata dischargenozzle is entered in each of the nasal passages. It

will be understood, also,`tl xt either form of construction can be used' for treating the va 6o rions passages of thevhuman bodywith either 'a powdered medicament or a liquid or vaporous mxtnre,the powdered medicament be ingpreferably used in connection .with a'solid ping or abutment and the liquid, or vaporous mixture for use'A in connection with a porous wall or abutment.

It will he seen that by means of the tor or instru-sent of the present inventi application of powder or liquid medic within the passage or passages to be t at the preex point of application i medicament reliably assured, `that. i from lumps or adhering particles is come, that tine distributing or applyin fopens the passage of the vagina oi passage for the reception of the medi( and the emi of such tube-cau be prop cated in rebelion to the place of treu that the powdered medicament and thi 'or vaporous mixture are both dischai a vaporized, showered, or sprayed ft rectly on tite diseased part., and that. eration of tine injector or' instrument d require any special skill, except in l the diseased partand properly direct distributing.: or applying tube to di thereon or inserting the discharge-ne the proper discharge, all oi' which ma injector or instrument very desirabl construction shown specially in Fig: .3 for use im treating diseases of the for which purpose this form of const is especially designed, and for intern.I ment of otherpassages, and the cons shown in Lgs. 3, 4, and 5 is speciali cable for the-treatment, of the lnasal-p \Vhat I regard as new, and desire t by Letters Patent, is-
